Gout diet. Uric acid comes from purines made naturally by your body as well as from purines in your diet. Avoid foods high in purines like red meats, organ meats, canned tuna, anchovies, mackerel, sardines, herring, mussels, scallops, shrimp and lobster. Avoid alcohol. Avoid sugar. Eat more plant-based proteins and drink lots of fluids. Choose low-fat or nonfat dairy products. The goal is uric acid <6.0.
Diet and gout. Avoid meats and most importantly, avoid organ meats; fatty meats and alcohol are doubly potent against gout. Avoid these. Also, if you are able, drink at least 3 liters fluid per day - this may enhance uric acid excretion - and if you incline your diet successfully to mostly whole grain, fruit, and veggies, using egg white for protein, then your uric acid levels will come down even more.
